Solar Water Heating in Nairobi

Ask most homeowners what quietly pushes up their electricity bill, and the water heater is often high on the list. Sunflow Systems is a Nairobi-based solar company that installs solar water heating systems, which use the sun’s heat instead of electricity to warm your water. We serve homes across Kenya on one-time or contractual terms, backed by 8+ years of experience and 450+ completed installations, and every system is designed to be reliable, efficient, and right for the household it serves.

How Solar Water Heating Actually Works

A solar water heating system has two main parts: collectors, usually on the roof, that absorb the sun’s heat, and an insulated tank that stores the hot water until you need it. Unlike solar panels, which produce electricity, collectors capture heat directly, which is why this is one of the most efficient ways to use solar energy at home. ENERGY STAR’s guide to how solar water heaters work explains the main system designs, noting that simple systems that heat household water directly in the collectors suit climates where freezing is rarely a concern.

The two most common collector types are flat-plate and evacuated-tube collectors, and both are named in Kenya’s Energy (Solar Water Heating) Regulations, 2012. Which one is right for your home depends on your roof, your hot water habits, and your budget. Our engineers work that out during a site assessment, so you aren’t guessing.

Questions Homeowners Ask Us

Will I still have hot water on cloudy days or at night?

Yes. Solar water heating systems are normally paired with a backup heater, either an electric element or your existing water heater, that tops up the temperature when the sun isn’t enough. You get hot water whenever you need it, and the sun does most of the work.

Can it work with the water heater I already have?

In many homes, yes. The solar system pre-heats the water, so your existing heater only has to top it up. We confirm this during the site assessment before recommending anything.

What size system does my home need?

That depends on how many people live in the house, how much hot water you use, and how much suitable roof space you have. We size every system to your household rather than selling a one-size-fits-all package.

Does it need much maintenance?

A well-designed system needs little day-to-day attention, but periodic servicing keeps it efficient and protects your investment. That is where our contract option comes in.

One-Time Installation or a Service Contract?

Some homeowners want the job done properly, handed over, and left to run. That is our one-time engagement: we assess your property, design the system, install it, and hand it over ready to use.

Others prefer to have us stay involved. Under a contractual engagement, we service and maintain your system after installation so it keeps performing year after year, with no chasing technicians when something needs attention.
